Experimental Procedure Part I - making scientific observations Set up 6

Experimental Procedure Part I - making scientific observations Set up 6 clean medium or large test tubes, and perform the following reactions and describe the evidence that a reaction has taken place. Make sure that all reactions are thoroughly mixed. Rxn A Add a pellet of solid sodium hydroxide (NaOH) to 5mLH2O in a medium test tube. Rxn B Place a 2 pea-sized amount of solid ammonium chloride (NH4Cl) into a medium test tube, and then add 5mLH2O. Rxn C Place 10 drops of aqueous silver nitrate (AgNO3) in a medium test tube and then add 10 drops of aqueous sodium chloride (NaCl). Rxn D Place 5mL hydrochloric acid (HCl) in a large test tube and then add a small pea size amount of solid zinc ( Zn,30 mesh). The boiling point is defined as the temperature at which the vapor pressure above the liquid (which results from volatility) is equal to the atmospheric pressure - you be learning about volatility, vapor pressure and boiling point in General Chemistry II. 8. Based on your observations, what do you think is happening chemically in tube A and tube B for this last pair of reactions
